This is redundant IMHO, as domcapabilities already reports, along with info about the usability. $ virsh domcapabilities | xmllint -xpath "//cpu/mode[@name='custom']/model[@usable='yes']/text()" - | sort 486 Broadwell-noTSX Broadwell-noTSX-IBRS Conroe core2duo coreduo Haswell-noTSX Haswell-noTSX-IBRS IvyBridge IvyBridge-IBRS kvm32 kvm64 n270 Nehalem Nehalem-IBRS Opteron_G1 Opteron_G2 Penryn pentium pentium2 pentium3 qemu32 qemu64 SandyBridge SandyBridge-IBRS Skylake-Client-noTSX-IBRS Westmere Westmere-IBRS Admittedly xpath is hairy, but the same info could be got with grep+awk if desired.
